摘要： An object is to provide a liquid ejecting apparatus that enables a liquid storage container to be properly and easily refilled with a liquid from a liquid refilling container without causing color mixture in the liquid storage container. The liquid ejecting apparatus includes liquid storage containers each configured to feed the liquid to a liquid ejecting portion and liquid refilling containers each configured to refill the liquid storage container with the liquid. A first fitting unit is provided around a liquid injection port in each of the liquid storage containers. A second fitting unit is provided around a liquid pour-out port in each of the liquid refilling containers. The second fitting unit is fitted to the first fitting unit to enable the liquid to be delivered from the liquid pour-out port to the liquid injection port.

摘要： An inkjet printing apparatus includes: a print head provided with an ejection opening surface; a tank; a supply flow path; a collection flow path; an intra-tank vacuum pump to reduce pressure inside the tank; and a control unit. The control unit performs a first operation and a second operation, the first operation causing the intra-tank vacuum pump to operate while a collection drive valve is closed, so as to pull out ink in a flow path which extends from the ejection opening to the supply flow path into the tank, the second operation causing the intra-tank vacuum pump to operate while a supply drive valve is closed, so as to pull out ink in a flow path which extends from the ejection opening to the collection flow path into the tank.
